Sony Corp. (6758) warned its 77 million PlayStation Network and Qriocity online service customers that their credit-card data, billing addresses and other personal information may have been stolen by a hacker.
"While there is no evidence at this time that credit-card data was taken, we cannot rule out the possibility," Patrick Seybold, a Sony spokesman, said on the company blog page. The hacker obtained user-provided names, e-mail addresses, birth dates, log-in information and purchase history, Seybold said,
Sony is likely to face questions about when it knew that customer data had been stolen and why it waited so long before issuing a statement.
The company said it had "no evidence" that credit card data had been obtained but was warning people "out of an abundance of caution".
Rik Ferguson, a senior adviser at the computer security firm Trend Micro, said gamers may have good reason for concern. He said: "People should keep a closer eye than usual on their bank and credit card accounts,"
